2.11 Thermal Specifications
The cooling solution of a COM Express
®
module is based on a heat-
spreader concept.
A heat-spreader is a metal plate (typically aluminum) mounted on the
top of the module. The connection between this plate and the module
components is typically done by thermal interface materials like phase
change foils, gap pads and copper or aluminum blocks. A very good
thermal conductivity is required in order to conduct the heat from the
CPU and the chipset to the heat-spreader plate.
The heat-spreader of the MSC module is thermally attached using
phase change materials and small aluminum blocks filling the gap
between CPU and chipset dies and the heat-spreader plate.
The heat-spreader is not a heat-sink!
It is a defined thermal interface
for the system designer with fixed mechanical dimensions, so it should
be possible to interchange different module types without problems.
There must be a cooling solution for the system. The surface
temperature of the heat-spreader should not exceed 80°C.
Main issue for the thermal functionality of a system is that each device
of the module is operated within its specified thermal values. The max
value for the CPU is 100°C (T die). So there may be system
implementations where the heat-spreader temperature could be
higher.
Anyway, in this case it has to be validated that there are no thermal
specification violations of any assembled part or integrated circuit over
the system temperature range even at worst case conditions.
Critical shutdown CPU temperature: approximately 130°C.
Throttling CPU temperature: 100°.
Operating at this temperature values reduces the reliability of the
module.
Environment: Ambient Temperature:
0°C … 60°C (operating)
-
25°C … 85°C (storage)
Humidity:
5 ... 95% (operating, non-condensing)
5 ... 95% (storage, non-condensing)
Additionally MSC offers adequate heat-sink solutions for the different
COM Express
®
modules depending on the power dissipation of the
implemented CPU. For more information please refer to
